Comments: Yes, you can do this. Check out the AJAX Control Toolkit sample site (which is currently available [here](http://ajaxcontroltoolkit.devexpress.com)) and select the ComboBox control from the left menu. All DropDownStyles allow you to search among all values in this control. Appropriate values will appear after you enter the first letter in the ComboBox control. If you need wider capabilities of the Rich Control, I recommend you try [DevExpress ASP.NET controls](https://www.devexpress.com/Products/NET/Controls/ASP/).
